Do You Know How Strong the Attraction of Neodymium Bar Magnets?

1. The attraction of neodymium bar magnets

Powerful magnets generally refer to neodymium iron boron magnets, which are artificial magnets that are among the best in all magnets. This kind of magnets are used in many industries. Neodymium iron boron magnets play an important role in the production of equipment, such as various mechanical equipment, electronic instruments and so on. So how strong is the attraction of this powerful magnet?

Under normal circumstances, neodymium bar magnets can absorb objects 600 times their own weight. The attractive force of a neodymium iron boron magnet has a certain relationship with its volume, performance grade, and distance.

The higher the grade of neodymium bar magnets, the greater the attractive force. For example, for magnets of the same size, N48 has a much higher attractive force than N35.

2. The specifications of neodymium bar magnets

The attraction distance of a neodymium iron boron magnet refers to the distance between the magnet and the adsorbed object. The greater the distance, the smaller the attraction. There are many specifications of neodymium bar magnets, with holes and special shapes. These are directly related to suction, and the calculation is more complicated. And different distances also have different suction power, and different materials or brands also have different suction power.

The suction formula of ordinary neodymium iron boron magnet: weight * 600 times = suction

PS: weight = volume * density

The suction formula of a circular neodymium iron boron magnet: volume * density * 600 times = suction
